| Protecting look up tables by mixing code and operations | 20130061061 | 20130307 |
 In the field of computer enabled cryptography, such as a cipher using lookup tables, the cipher is hardened against an attack by a protection process which obscures the lookup tables using the properties of bijective functions and applying masks to the tables' input and output values, for encryption or decryption. This is especially advantageous in a “White Box” environment where an attacker has full access to the cipher algorithm, including the algorithm's internal state during its execution. This method and the associated computing apparatus are useful for protection against known attacks on “White Box” ciphers, by obfuscating lookup table data, thereby increasing the cipher's complexity against reverse engineering and other attacks.

| Cryptographic process execution protecting an input value against attacks | 20130016836 | 20130117 |
 A cryptographic process (such as the AES cipher) which uses table look up operations (TLUs) is hardened against reverse engineering attacks intended to recover the table contents and thereby the cipher key. This hardening involves removing any one-to-one correspondence between the TLU inputs and outputs, by altering the output of the TLU dynamically, e.g. at each execution (call) of the TLU. This is done by increasing the size of the tables, applying a dynamically determined mask value to the table input and/or output, or using an inverse of the table.

| Decryption key table access control on asic or assp | 20070098149 | 20070503 |
| An ASIC or ASSP has processor circuitry (110), a predetermined initialization program (100) for execution by the processor circuitry at power up, and a non-volatile key table (120) readable by the initialization program, and not accessible otherwise by the processor circuitry. The initialization program reads a key index associated with encrypted data, from external memory, and uses the key index to read a corresponding key from the table, to decrypt the encrypted data for use by the processor circuitry. Optionally another key is first decrypted and used for the decryption of the encrypted data. By keeping the key on board the chip and restricting access in this way, the key and therefore the encrypted data can be protected from software based reverse engineering. This means the... |

| Attack resistant phishing detection | 20070005984 | 20070104 |
| A phishing detection server component and method is provided. The component can be employed as part of a system to detect/phishing attacks. The phishing detection server component can receive password reuse event report(s), for example, from a protection component of client component(s). Due to the malicious nature of phishing in general, the phishing detection server component can be susceptible to attacks by phishers (e.g., by reverse engineering of the client component). For example, false report(s) of PREs can be received from phisher(s) in an attempt to overwhelm the server component, induce false positives and/or induce false negatives. Upon receipt of a PRE report, the phishing detection server component can first verify that the timestamp(s) are genuine (e.g., previously generated by the phishing detection server component).

| Method and device for protection of an mram device against tampering | 20060179490 | 20060810 |
| Data, stored in MRAM-cells (12) should be protected against misuse or read-out by unauthorised persons. The present invention provides an array (10) of MRAM-cells (12) provided with a security device (14) for destroying data stored in the MRAM-cells (12) when they are tampered with. This is achieved by placing a permanent magnet (16) adjacent the MRAM-array (10) in combination with a soft-magnetic flux-closing layer (18). As long as the soft-magnetic layer (18) is present, the magnetic field lines (20) from the permanent magnet (16) are deviated and flow through this soft-magnetic layer (18). When somebody is tampering with the MRAM-array (10), e.g. by means of reverse engineering, and the flux-closing layer (18) is removed, the flux is no longer deviated and affects the nearby MRAM-array (10),... |

| System and method for reverse engineering of pattern string validation scripts | 20060075392 | 20060406 |
| A system and method for reverse engineering of pattern string validation scripts is presented. A pattern engine receives an input string from a developer or a database, and generates a pattern string based upon the input string and strictness preferences. The strictness preferences identify how much to constrain generated pattern elements that are included in the pattern string. Once the pattern engine generates the pattern string, the pattern engine creates a user-friendly format string that is used by a developer to assess pattern string adjustments. The pattern engine may operate in a single mode or a multi-mode. In a single mode, the pattern engine uses a single input string to generate a pattern string. In a multi-mode, the pattern engine uses multiple input strings, typically from... |
